CVE-2020-15505: Ivanti MobileIron Multiple Products Remote Code Execution Vulnerability

CVE-2020-15505 is a remote code execution vulnerability affecting multiple Ivanti MobileIron products, including Core & Connector, Sentry, and Monitor and Reporting Database (RDB). An attacker who can reach a vulnerable instance may be able to run code on the system, which can lead to full compromise of the MobileIron deployment and any devices or data it manages. Because MobileIron is commonly used for enterprise mobility management, successful exploitation can give an attacker a foothold inside the organization. Confirm exact product coverage and impact against the vendor advisory.

How it works

The weakness is tracked as CWE-706 (Use of Incorrectly-Resolved Name or Reference). Public detail describes an unspecified flaw in the listed Ivanti MobileIron products that allows remote code execution. In general terms for this class of issue, an attacker sends crafted input that causes the application to resolve a name or reference incorrectly, leading to unintended code execution on the server. No further exploit mechanics are provided in the available facts; treat the vulnerability as a network-reachable RCE condition on the affected MobileIron components and verify technical details only from the vendor advisory. Do not assume authentication requirements, specific protocols, or payload formats beyond what the advisory states.

Am I affected? How to find it in your systems

Ivanti MobileIron Core & Connector, Sentry, and Monitor and Reporting Database (RDB) are typically deployed as on-premises or managed appliances/servers that handle mobile device enrollment, policy enforcement, app distribution, and related monitoring. These systems often sit in DMZs or internal management networks and may be reachable from the internet or from large numbers of managed endpoints.

• Inventory all hosts and appliances running MobileIron/Ivanti Endpoint Manager Mobile (or legacy MobileIron branding) software; check configuration management databases, vulnerability scanners, and network device inventories for the product names Core, Connector, Sentry, and RDB.
• Confirm installed versions and build numbers directly against the vendor advisory; the facts do not list specific affected or fixed versions, so do not rely on informal version ranges.
• Review network exposure: identify which instances accept inbound connections from untrusted networks and whether management interfaces are internet-facing.
• For exploitation signs, examine application and system logs on the MobileIron hosts for unusual process creation, unexpected outbound connections, or authentication and request anomalies around the time of any suspected activity. Correlate with endpoint and network telemetry. Specific indicators of compromise are not supplied in the facts; obtain them from the vendor or your threat-intelligence sources if available.

How to remediate

Patch first. Apply the updates published by Ivanti for the affected MobileIron products exactly as directed in the vendor advisory and in line with CISA’s required action to apply updates per vendor instructions. After patching, verify the new versions are running and that the services restart cleanly.

• Rebuild or re-image appliances if the vendor recommends it for complete remediation of this class of flaw.
• Restrict administrative and management interfaces to trusted networks and jump hosts only.
• Enforce least privilege on service accounts used by Core, Connector, Sentry, and RDB components.
• Ensure the MobileIron deployment is covered by regular vulnerability scanning and configuration baselines so future issues are detected promptly.

If you can't patch immediately

Until the vendor update can be applied, reduce exposure with compensating controls appropriate to a remote code execution vulnerability on a mobility-management platform.

• Segment the MobileIron hosts so they are reachable only from required management and device networks; block direct internet access to management ports where possible.
• Place a web application firewall or reverse-proxy filter in front of any externally facing interfaces and enable rules that constrain unexpected request patterns; treat this as temporary virtual patching and tune it carefully to avoid breaking legitimate device traffic.
• Disable or restrict any non-essential features, connectors, or reporting interfaces that are not required for operations, after confirming impact with the vendor documentation.
• Increase monitoring and alerting on the affected systems: process creation, new listening ports, unusual outbound connections, and changes to critical configuration files. Retain logs for later forensic review.
• Limit the number of administrators and require strong authentication for all management access.

If your data may have been exposed

Actively exploited remote code execution vulnerabilities can lead to full system compromise and subsequent data theft or further lateral movement. The available facts do not document ransomware use for this CVE. If you suspect exploitation, isolate the affected hosts, preserve logs and disk images, and follow your incident-response process. As a further check, you can run a free exposure scan of your email addresses against known breach data to see whether credentials or personal information have appeared in prior public breaches.
